Özet

Beetles in the genus Copris (Coleoptera: Scarabaeidae) are coprophagous insects colloquially referred to as "tunnelers" due to their behavior of creating channels in feces. These beetles utilize dead organisms and non-living organic matter as food sources, playing a vital role in nutrient cycling and contributing to the survival of other organisms in their ecosystem. To date, no studies have investigated the hindgut in Copris. This study aims to detail the histomorphological structure of the hindgut of Copris felschei Reitter, 1892 (Coleoptera: Scarabaeidae) using light and scanning electron microscopy. The alimentary canal in Coleoptera generally consists of three main sections: the foregut, midgut and hindgut, with C. felschei's hindgut primarily comprising the ileum, colon and rectum. The anatomical and histological characteristics of the ileum and colon are almost similar, covered by the Malp൴gh൴an tubules' d൴stal ends. Scann൴ng electron m൴croscopy ൴mages (SEM) revealed a s൴gn൴f൴cant presence of muscle t൴ssue surround൴ng the ൴leum and colon surfaces. Their epithelium is cylindrical, featuring visible oval nuclei bordered by a thin cuticle. The rectum connects the colon to the anus and is surrounded by intima, a single layer of squamous epithelium, and a thick muscle layer. These findings are expected to enhance our un
